NEW YORK, Jan 19 (Reuters) - New York state"s attorney general has accused Donald Trump"s family business of repeatedly misrepresenting the value of its assets to obtain financial benefits, citing what it said was significant new evidence of possible fraud. The accusations by Attorney General Letitia James mark a substantial escalation of her civil probe into the Republican former U.S. president"s business, the Trump Organization, and the roles of his adult children. They are part of her effort to force Donald Trump and his children Donald Trump Jr and Ivanka Trump to comply with her subpoenas to testify under oath, which the family has asked a judge to block. Neither Trump nor his children have been accused of criminal wrongdoing. While James cannot file criminal charges because her probe is civil, she can sue the Trumps and the company. Trump has called the nearly three-year probe by James, a Democrat, a political "witch hunt." In filings late Tuesday with a New York state court in Manhattan, James described what she called misleading statements about the values of six Trump properties, as well as the "Trump Brand." The properties are golf clubs in Aberdeen, Scotland, and suburban Westchester County near New York City, the Seven Springs Estate in Westchester, buildings on Wall Street and Park Avenue in Manhattan, and Trump"s penthouse in Trump Tower. James has been investigating whether real estate values were inflated to obtain bank loans and reduced to lower tax bills. Her filing described evidence of misstatements to lenders, insurers and the Internal Revenue Service. James wants a judge to order the Trumps to testify within 21 days. "We have uncovered significant evidence that suggests Donald J. Trump and the Trump Organization falsely and fraudulently valued multiple assets and misrepresented those values to financial institutions for economic benefit," James said in a statement. "The Trumps must comply with our lawful subpoenas for documents and testimony because no one in this country can pick and choose if and how the law applies to them," she added. "UNFOUNDED ATTACKS" Alina Habba, a lawyer for Trump, in a statement called James" accusations "merely the latest in a long line of unfounded attacks against my client and an obvious attempt to distract the public from her own inappropriate conduct. Letitia, you are not above the law." The Trump Organization in a statement said it will defend against James" "baseless" accusations, accusing her of twisting the facts and misleading the public because she faces "the stark reality that she has no case." James" probe also partially overlaps a criminal probe by the office of Manhattan District Attorney Alvin Bragg, which James joined in May, into the Trump Organization"s practices. Lawyers for the Trump family have argued that James" subpoenas are an improper means to gather evidence in the civil probe that could then be used in the criminal probe. Alan Futerfas, a lawyer for Donald Trump Jr and Ivanka Trump, in a statement said James" filings did not address her "repeated threats to target the Trump family" and ignore their constitutional rights by conducting overlapping probes. In July, the Trump Organization and its longtime Chief Financial Officer Allen Weisselberg pleaded not guilty in the criminal probe to charges they awarded "off-the-books" benefits to company executives in a 15-year tax fraud. Eric Trump, another of Donald Trump"s adult sons, testified under oath in James" civil probe in October 2020, and according to her invoked his constitutional right against incriminating himself more than 500 times in six hours. FINANCIAL CONDITION Many of James" accusations center on Donald Trump"s annual "statements of financial condition," which give lenders and other counterparties the values and liabilities associated with various assets. James said she found evidence that Trump was "personally involved" in approving the statements, and used them "in numerous commercial transactions for his own financial benefit." She said one statement in June 2015 valued Trump"s building at 40 Wall Street at $735.4 million, tacking on nearly $200 million to its appraised value, a mere eight months after one lender valued the same building at $257 million. James said Trump inflated the values of the Scotland golf club and Seven Springs in part based on assumptions that residential housing could be built there. She also said Trump in his 2015 and 2016 statements overstated the value of his penthouse apartment, putting it at $327 million by claiming it contained 30,000 square feet and not the 10,996 square feet described in various documents he signed. Under questioning by her office, Weisselberg conceded that "this amounted to an overstatement of "give or take" $200 million," James said in a filing. Last month, Donald Trump sued James in a federal court in Albany, the state capital, to halt her civil probe, calling it a means to harass and intimidate a political opponent.
